如何更改 graphviz 的默认字体大小?
我使用 doxygen + graphviz 来记录我的代码。 graphviz 在生成图像方面做得很好。
有什么方法可以更改 graphviz 的默认字体大小吗?默认值为 14,但我想使用 12。
更改单个元素(例如节点、子图、边缘...等)的字体大小确实很痛苦。
更新:
这里参考的是我在 doxygen 中使用的代码(当然,文本字段已重命名)
@dot
strict digraph {
node [shape = box, fontsize = 12];
subgraph cluster_main {
fontsize = 12;
shape = box;
label = "main";
subgraph cluster_main_common {
fontsize = 12;
shape = box;
label = "common";
subgraph cluster_main_common_source {
fontsize = 12;
shape = box;
label = "source"
subgraph cluster_file1 {
fontsize = 12;
shape = box;
label = "file1.c";
gSystem [label = "var1" URL = "\ref var1"];
}
subgraph cluster_file2 {
fontsize = 12;
shape = box;
label = "file2.c";
gCard [label = "var2" URL = "\ref var2"];
}
subgraph cluster_file3 {
fontsize = 12;
shape = box;
label = "file3.c";
gPwrSupply [label = "var3" URL = "\ref var3"];
}
}
}
subgraph cluster_main_docs {
fontsize = 12;
shape = box;
label = "docs";
subgraph cluster_main_docs_features {
fontsize = 12;
shape = box;
label = "features";
subgraph cluster_main_docs_features_source {
fontsize = 12;
shape = box;
label = "source"
subgraph cluster_file4 {
fontsize = 12;
shape = box;
label = "file4.c";
deviceInfo [label = "var4" URL = "\ref var4"];
}
}
}
}
}
}
@enddot
I use doxygen + graphviz for documenting my code. graphviz does a nice job of generating images.
Is there any way to change the default fontsize for graphviz? The default is 14, but I want to use 12 instead.
Its a real pain to change the fontsize for individual elements like, nodes, subgraphs, edges ... etc.
UPDATE:
For reference here is the code I'm using in doxygen, (the text fields have been renamed, of course)
@dot
strict digraph {
node [shape = box, fontsize = 12];
subgraph cluster_main {
fontsize = 12;
shape = box;
label = "main";
subgraph cluster_main_common {
fontsize = 12;
shape = box;
label = "common";
subgraph cluster_main_common_source {
fontsize = 12;
shape = box;
label = "source"
subgraph cluster_file1 {
fontsize = 12;
shape = box;
label = "file1.c";
gSystem [label = "var1" URL = "\ref var1"];
}
subgraph cluster_file2 {
fontsize = 12;
shape = box;
label = "file2.c";
gCard [label = "var2" URL = "\ref var2"];
}
subgraph cluster_file3 {
fontsize = 12;
shape = box;
label = "file3.c";
gPwrSupply [label = "var3" URL = "\ref var3"];
}
}
}
subgraph cluster_main_docs {
fontsize = 12;
shape = box;
label = "docs";
subgraph cluster_main_docs_features {
fontsize = 12;
shape = box;
label = "features";
subgraph cluster_main_docs_features_source {
fontsize = 12;
shape = box;
label = "source"
subgraph cluster_file4 {
fontsize = 12;
shape = box;
label = "file4.c";
deviceInfo [label = "var4" URL = "\ref var4"];
}
}
}
}
}
}

Fontsize 是一个图属性(以及边和节点属性)。 Doxygen 生成一个点文件,因此,例如:
特定设置将覆盖通用设置;因此,将 fontsize 设置为节点属性将覆盖设置为图形属性的 fontsize(尽管仅适用于节点),并且为特定节点设置 fontsize 将覆盖为所有节点设置的 fontsize。
如果您尝试我上面的方法,但它似乎不起作用,请更改字体大小,在整个点文件中搜索“字体大小”设置,删除它们,然后将字体大小重新设置为节点属性。
这是完整的 graphviz 属性列表。
Fontsize is a graph attribute (as well as an edge and node attribute). Doxygen generates a dot file, so, e.g.,:
Specific settings will override generic ones; hence setting fontsize as a node attribute will override the fontsize set as a graph attribute (just for nodes though), and setting fontsize for specific nodes will override fontsize set for all nodes.
If you try what i have above and it does not seem to work, change the fontsize, search your entire dot file for 'fontsize' settings, remove them, and re-set fontsize as a node attribute.
Here is the complete graphviz attribute list.
